IMPROVEMENT IN DEVICES FOR ATTACHING PRESSER-FEET TO THEIR BARS.

Specification forming part of Letters Patent 110.158.,744, dated January12, 1875; application filed December 15, 1874.

To all whom it may concern:

- Be it known that I, JOHN J'. SCHNEIDER, of

Machines to their Bars, of which the following is a clear, full, andexact description, reference being had to the accompanying drawingsmaking a part of this specification, in

- which-- Figure 1 is a perspective view ofa presserfoot with myimprovement attached. Fig. 2

' shows the presser-foot bar with the presserfoot detached. Fig.3 is avertical section.

'Fig. 4 is. a view of the bottom of the device.

My invention has reference to the 'pre'sserfeet, and all attachmentsadjustable to the pres ser-bar, of all the difl'erent kinds of sewing-lnachines, but more particularly the Singer machine, in which thepresser-foot is secured by means of a screw, which soon becomes worn andis liable to break, and which is inconvcnicnt to manage in adjusting thepresserfoot; and it consists in the combination of the several deviceshereinafter described and explained. V

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawings, A represents the presser-' foot bar of sewing-machine,and B the presserfoot. Across the hollow shank or upper por tion of thepresser-foot is secured the small in place, the outer end of the keyresting in a recess in the lower part of the shank of the .presser-foot,as shown in Fig.3.

It is evident, from the above description, that the presser-foot orother attachment can only he removed from the bar by pressing the.

lever 0 toward the bar, and thus withdrawing the key 0 from contact withthe presser-foot,

when the latter can readily be removed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The slotted presser-foot bar "A, provided with the spring-lever U andkey 0, in combination with the presser-foot B, having the small bar a,substantially as and for the 'pur-' pose set forth.
